J'Karl was a space traveler of an unnamed species who became trapped in the netherspace containing the Museum of Missing Ships.
History[]
When a group of Klingons seized the Museum and captured its inhabitants, J'Karl was willing to fight back, and shamed Sprang for his reluctance to do so. He joined James T. Kirk in battling the Klingons. J'Karl died along with the other inhabitants of the Museum when Limbo exploded, having lived there so long that they would be out of place in Kirk's world.
